Resource Leak Vulnerability in Linux Kernel SPI Device Setup

CVE-2026-46083

What is CVE-2026-46083?

The Linux kernel's SPI subsystem faced a resource leak issue during the device setup process. Specifically, if the spi_setup() function failed while attempting to register a device, it could lead to unfreed resources that were allocated during the setup phase. The vulnerability has been addressed to ensure that proper cleanup mechanisms are invoked, preventing resource leaks and maintaining system stability during device initialization.
